Specification of Letters Patent.

Patented Nov. 6, 1906.

Application filed January 31, 1906. Serial No. 298,820.

To all whom it may concern:

Be it known that I, FRANKLIN S. TAYMAN, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Driers, of which the following is a specification.

' My invention relates to driers of the vertical stack type in which an endless carrier for the material to be dried is arranged within said stack.

My invention comprises certain im rovements in driers of this character, inc uding means for effecting a proper distribution of the heated air within the stack, the automatic exhaustion of the moisture, and automatically-operated means for s rinkling the dried material preparatory to the further manipulation of the same.

My invention is fully shown in the accompanying drawings, in whichigure 1 is a sectional elevation of a stackdrier made in accordance with my invention, taken on the line a a, Fig. 2. Fig. 2-is a sectional plan view of the drier, taken on the line b b, Fig. 1. Fig. 3 is a sectional elevation at right angles to Fig. 1, taken on the line 0 c, Fig. 2 and Fig. 4 is a view in elevation bf the upper part of the stack, partly broken away an showing the mechanism for operating the movable roof. Fig. 5 is an enlarged'view of the lower part of the stack, showing the spraying mechanism in action. Fig. 6 is a sectional view of the valvescontrolling the spraying means and the means whereby said valves are operated; and Fig. 7 is a diagrammatic view, on a reduced scale, of a stack having a modified form of conveyor.

Although the structure forming the subject of my invention may be employed in any laundry for the purpose of drying various ar ticles of wearing-apparel preparatory to ironing the same and may further be employed for drying other material, it has been desi ned especially for the purpose of drying w to linen or duck coats.

In the drawin s, 1 represents the stack, having hollow wa ls 2, which serve as a means of passing the warm air leaving the stack at various points 3 throughout its length to a fan-blower 4, located'outside the stack,

whereby it is returned to said stack at the bottom of the same.

.provide a series of Arranged Within the stack and suitably journaled on shafts or spindles 5, carried by suitable brackets 6, secured to the walls of said stack,. are a series of sprocket-wheels 7, over which the chains 8 pass, which chains are connected together by rods 9, upon which the coats, other dried may be hung.

In the shaft 10, carrying a worm-wheel 11, which receives power from a worm 12, mounted on a shaft 13, suitably journaled and driven in any suitable way from any suitable source of power-for instance, by a belt 14 from a uley 15 on the power-shaft 16. The s roo etwheels 7 are driven from the sha t 10 by meansof a chain 17, which passes around a wheel 18 on said shaft and around a wheel 19, connected to turn with one of said sprocket- Wheels 7 In the lower part of the stack I steam-pipes 20, disposed upper' part of the stack I mount a.

garments, or other material to be over the bottom and adjacent the four walls of the same and extending u wardly for a distance of four or five feet, eing suitably connected with a source of steam generation. These pipes create a very hot zone at the base of the stack and serve to heat the inconiing air from the fan-blower.

- In order to distribute throughout the stack the heated air collecting therein, I provide the fan-blower 4, mounted on the outside of I the stack at the base of the same, having an intake 21 connected to the hollow wall of the stack and an outlet 22 ator near the floor of said stack. To distribute the air from said blower, to the floor or bottom of the stack-well and having side deflectors 24, which cause the air blown into the stack "to rise in different currents and thoroughly permeate the material or garments to be dried;

The air in the stack necessarily becomes very moist, due to *the extraction of the moisture from the Wet garments or other material therein, and to afford some exhaust therefor and expedite the drying operation I provide a roof composed of sections 25 and 26, hinged at 27, and means, as shown in Fig. 4, to lift the same at intervals. The section 25 of the roof is provided with an arm 28, extending beyond the ed e of the same, which arm is connected by a c ain or cord 29 I provide a series of vanes 23, secured to one end of a lever 30, pivoted at 31 on the side of the stack. On the shaft 10 I mount a cam 32, adapted to engage the opposite end. of said lever at regular intervals and by raising said. end depress the opposite end connected to the roof-section 25, whereby said roof-sections will be turned on their pivots and the outer ends raised at regular inter vals.

Although I have shown small sprocketwheels 7, around which the chains 8 pass, it will be understood that I may employ single sprocket-wheels 7 of enlarged size at top and bottom of the stack, over which the chains 8 may pass, as shown in the diagram view Fig. 7, without departing from my invention.

After the coats or other garments have been dried in the starch it is necessary to sprinkle the same before they may be ironed, and it is often desirable to s rinkle other ma terial after the same has een dried. For this pur ose I provide a sprinkling device, an enlarge view of which 1s shown in Fig. 5. This comprises a pipe 35, having a pair of erferated arms 36, disposed adjacent to the Tower run of the chains carrying said garments, coats, or other material, which pipes are connected by a Y-coupling 37 with steam and Water supply pipes 38 and 39, respcc tively, Whereb the material or garments may be sprayer and the latter thereby dampened suiiiciently to insure the proper ironing of the same. This spraying attachment is designed to be operated automatically after the material or garments have reached a dry condition, and for this purpose the following means are employed: Carried by one of the chains 8 at suitable intervals,'being disposed in proper osition with relation to the rods 9, carrying the coats or other garments, are the rollers 41. Each of the pipes 38 and 39 are provided with valves arranged to open against the pressure, being normally held to their seats by such pressure and also by suit able springs. Each valve has a stem projecting through the casing, and these stems are joined by a cross-bar 43. This cross-bar is provided with a stem 44, disposed in a casing 45, carried by the stack, a spring is be ing provided to keep it normally in the raised position, although the s rings holding the valves to their seats may fie sufficient to keep this stem raised. Disposed atthe top of this stem is a plate 47, and pressure being applied to this plate the stem 44 will be depressed, opening the valves in the pipes 38 and 39, andsteam and water will be discharged simultaneously in the form of spray through the perforations of the pipe-arms 36. The plate 47 is depressed by the rollers 41 to cll'ect the opening of the valves, and this plate is curved, so that the pressure may be maintained for a suliicient length of time to cfiect the desired dampening of the garments or otheranaterial. The forward end senses of this plate is also curved, so that the rollers can readily ride onto the same.

As it is only necessary to spray the ma.- terial after it has been thoroughly dried or to dampen the garments after they have been dried in the starch, the plate 47 is hinged at 48, as clearly shown in Fig. 6, so that it may be turned out of the way during the timethe garments are being dried.

The stack has openings 49 for access to and examination of the conveyor and the material carried thereby, such openings being closed by doors.
